作为菜鸟,理论上有一定的了解,但是如何apply to the real project at work,还是
心比较虚。所以,是否请大拿们照顾我这样的, 用工作中的实际例子来说明一些具体
的feature, 比如,index, constraints, trigger, stored procedure, join, view,
CTE, xml, function, tuning, etc. 然后可以引申出去,一些变化,大家也可以就此
发表评论,质疑,或者胡言乱语等等。 这样水量也增加了,大家各取所需。。。

If you have used some really heavy Javascript web app, you will immediately
notice the difference.
In minefield, or Safari, for example, in MobileMe.com's calander web app,
you click something, a tab will animate and pop out, it is instant in these
two browsers. However, even you use the latest Opera weekly, it will still
take about 2 seconds and more on a slow machine.
And these Javascript speed is something worth optimizing because Apple,

Passing acid tests is only HALF of the story. It only means

There are a lot of ambiguities in CSS and HTML specifications
in specific areas. The problem gets worse when JavaScript is
involved in manipulating them. There are issues of reading
and writing DOM / CSS values. Safari sucks because of these
unfriendliness. Remember that gmail was last supported on

It was last supported, because IE and Firefox have the majority of market
share.
However Safari now has significant market share, combined with Chrome,
people will make their service compatible. Esp. google.
and you mentioned different tests
But without you actually test it, it means nothing.
I am pretty sure Safari's performance is excellent when judged by different
browser benchmarks.

Because you developed for IE, whose standard appliance is the worst among
ALL browsers, I am not convinced that your DOM /CSS script is "correct" or
standard.
Opera and Firefox are famous for rendering non-standard code just to look "
correct", and correct is defined by looking the same as IE.
Moreover, you mentioned your script has glitches on both Firefox and Opera.
I think this totally suggest the quality of your work: IE only.

I guess that you are not a JavaScript developer, because you obviously
didn't know that no JavaScript code involves DOM / display can work
100% identical (pixel precise that is). You obviously didn't know
that CSS and HTML have many subtle places where interpretations can be
different. JS development always start out from a browser and then extends
to other browsers to address minor glitches (interpretation differences).
